I just completed all the mod to my 9x by adding the Frsky module, but I have a question about getting power to the V8 receivers. I have two receivers, V8R4 and V8FR-II. The V8R4 only has four servo connections, and the V8FR only has eight. I fly electric and use a BEC to power the receivers. How do I hook up the power? I am using all the channels for servos and ESC, so I have not free slots.

Use a "Y" harness into any channel on the 4 channel. Battery into one output, servo into the other. I have several of these RX's and they work very well with surprising range. I fly a .40 powered funfly planes with 2 of them and have never had a glitch.
